What to do if…
your phone battery is low and your ticket or access pass is stored only on your phone

Short answer

Get your ticket/pass visible in an offline-ready form immediately, then go to a staffed point (ticket office/gateline/help point) before you’re challenged, while you still have enough battery to show it.

Do not do these things

  • Don’t keep the ticket app open at full brightness “just in case” — it can drain the last few % fast.
  • Don’t wait until you’re at the barrier or in front of an inspector to mention it; act while you still have power.
  • Don’t assume you’ll have signal to load your ticket at stations, underground areas, or on platforms.
  • Don’t rely on screenshots unless your operator explicitly says they’re accepted (many don’t accept them).
  • If you’re using pay as you go/contactless on a phone, don’t start a journey if you think the phone may die before you can finish any required “touch out” step.
  • Don’t hand your unlocked phone to strangers to “help” — keep control of it.

What to do now

  1. Preserve battery immediately (30 seconds).

    • Turn on Low Power Mode.
    • Turn down brightness.
    • Close other apps.
    • Turn off Wi-Fi/Bluetooth unless your ticket/pass requires it.

  2. Make the ticket/pass work without signal (do this before moving).

    • Open the ticket and get the barcode/QR ready.
    • If your operator/app offers it, download the eTicket in-app or add it to your mobile wallet.
    • If your ticket is a PDF eTicket from an email/receipt, download it to your phone so it opens offline.
    • Quick offline check: switch to Airplane Mode for a moment and confirm the ticket still displays. (Turn it back off if you need data again.)

  3. Go to staff while you still have battery.

    • At stations: go to the ticket office (if open), a staffed gateline, or use the Help Point.
    • Say: “My ticket is only on my phone and the battery is about to die — can you help me verify it or advise what to do before I travel?”

  4. If you’re already onboard and worried about inspection, show it early.

    • If you see staff or an inspection is likely, approach when practical and show the ticket immediately while it still loads.
    • Have your booking reference, route, and travel time ready in case they need to verify details.

  5. Get power quickly (even a brief top-up helps).

    • Ask staff if there’s a charging point nearby.
    • If you have a cable, ask a café/shop if you can use a socket briefly.
    • If you must buy something now, prioritise a small power bank or the correct charging cable.

  6. If you’re using pay as you go/contactless on a phone, reduce risk.

    • If you haven’t started yet and you have another option, use a physical contactless card instead of a phone.
    • If you’ve started a pay as you go journey and fear the phone may die, focus on preserving enough power to complete any required “touch out” step.

What can wait

  • You do not need to argue policy, chase refunds, or appeal anything right now.
  • You do not need to set up perfect backups for every future journey today.
  • You do not need to diagnose why your battery is draining — just stabilise this trip first.

Important reassurance

This is a common, solvable travel problem. Acting early — making the ticket work offline and speaking to staff before you’re stuck — is what usually prevents it turning into a bigger issue.

Scope note

These are first steps to get you through the next barrier/inspection/boarding. Operator-specific follow-ups (fare adjustments, penalty fare appeals, refunds) can be handled later, when you’re not under time pressure.

Important note

This is general information, not legal advice. Rules vary by operator and ticket type (including whether screenshots are accepted). If you’re unsure, follow your operator/app instructions and ask staff as early as possible.
